Parameters for Distributing Transports 
Logging on to the SAP System
An important
tp parameter is the name of the SAP System which tp should log on to. This is not a parameter that can be set in the transport profile. You set it implicitly by making entries in the command line when tp is called. The name of the SAP System is included as one of the arguments in the command line, or it can be determined from the first three characters of the change request specified (for export calls).Additional Parameters
Default value: 0
Value range: Boolean
You can use this parameter to make a dummy system known in the global parameter file. Imports are not performed for an SAP System with
dummy=1 .Default value: 1
Value range: Boolean
The parameter
testimport = 0 prevents the transport control program tp from performing a test import after the export (for example, when the target system is "remote"). You must specify the parameter for the source system of the transport request.Value range: Text
You can define a list of up to 50 SAP Systems with this parameter. The names must be separated by commas. If the export of a change request is successful,
tp determines the test systems that have been specified for the target system of the change request and places the request in the buffers of these test systems.
